The scar after anal hemorrhoid or anal fistula surgery needs more than half a year to gradually soften. Postoperative uterine contractions and foreign body sensation are normal. You can use local hot compress and then apply medicinal ointment to the anus, which will help you recover as soon as possible. Anal fistula is easy to recur, so special attention should be paid to anal nursing to prevent recurrence! It is suggested that you prepare an electric anal nursing bag, which has an anal cleaner to help you clean after defecation, and the anal medicine barrel is fumigated and bathed with potassium permanganate, and the anal support pad helps to suspend the wound and promote the edema to subside. Hospitals are twice as expensive as online, but you should pay attention to identification when buying treasures, and be careful to buy fake goods that look cheap. For example, all hospitals use four air passages. When you open the cover, you can see two hidden airways, which can ensure the wound to breathe freely, but there is no airway at all. Other patients opened their coats, and the result was a black core, which was very soft to sit on and collapsed as soon as they sat down.
